MD - thighboard

It is well to parenthesize here, that of the fatal accidents in the Sperm-Whale Fishery, this kind is perhaps almost as frequent as any. Sometimes, nothing is injured but the man who is thus annihilated; oftener the boat’s bow is knocked off, or the thigh-board, in which the headsman stands, is torn from its place and accompanies the body. But strangest of all is the circumstance, that in more instances than one, when the body has been recovered, not a single mark of violence is discernible; the man being stark dead.
